Hi All! I recently flashed the ECU with FVD's software, drove for a few days and then did the de snorkel. A few days later the CEL came on and it's reading P0139 and P0159 anyone else have this problem? suggestions for O2 sensors(brand)?

ive never heard of a de-snork throwing a code... have you done anything else?

haven't done anything else except those two

there are a couple tricks to checking if the O2s are bad but u will have to search them out. if they are bad i cant imagine it was the snorkel's fault but you can call FVD and ask them whats up. im sure they have some insight :dance:

Borg Warner makes a O2 sells for $25. but you have to splice it to your wires
